DEVICE FOR USE FOR SPRAYING- PURPOSES.

Application filed October 20, 1913. Serial No. 796,241.

To all whom it may concern:

Be it known that I, FREDERIC D. HOUGH- TON, a citizen of the United States, residing at Worcester, in the county of Worcester and State of Massachusetts,have invented a new and useful Device for Use for Spray-' ing Purposes, of which the following is a specification.

This invention relates to a device for holding a soluble or partially soluble insecticide, disinfectant, cleaning compound or the like, in such a manner that it can be dissolved and applied by the forcing of a stream of water therethrough.

The principal objects of the invention are to provide an inexpensive and simple construction for this purpose and especially to provide one of such character that the strength of the solution will not decrease as the material is gradually dissolved during the use of the device.

The invention also involves improvements in details of construction which will appear hereinafter.

Reference is to be had to the accomp'anys ing drawings in which Figure 1 is a side view of a device constructed in accordance with this invention shown as applied to a hose in condition for use; Fig. 2 is a central longitudinal sectional view thereof on enlarged scale; Fig. 3 is a side elevation of the holder for the material to be dissolved with the parts partially separated; Fig. 4 is a side view partly in central section showing a modification; Fig. 5 is a longitudinal central section of another modification; Fig. 6 is a transverse section of the interior parts thereof; and Fig. 7 is a side view of the wire cloth portion partly straightened out.

Several devices have been invented for the purpose of holding soaps and other sol-v uble material for the purpose of spraying trees, plants, buildings, etc. difficulties with these devices, so far as I am acquainted with them, is the fact that the solid or viscous substance placed in thedevice is gradually dissolved so that its external surface decreases in area as it is used. Thus the longer it is used the weaker is the solution sprayed from it.

One of the objects of this invention is to provide an arrangement whereby the- Specification of Letters Patent.

strength of the solution will keep up even when the amount of material left in the device is very greatly decreased from the normal amount.

In the drawings, a. cylindrical receptacle 10 shown as formed of thin sheet metal is arranged 111 the usual way with coupling sections 11 and 12 on the two ends constitut ng respectively, an inlet and anoutlet,

so that it can be inserted in the line of hose. will also pass through the device and dissolve the material therein. In the present case, however, the receptacle or can 10 is provided with a solid head 13 on which the outlet 12 is formed and with a removable cover 14 at the other end having an ppeiiing therein from which projects the in- For the purpose of properly holding the material to be dissolved, a wire cage 15 is inserted in the can or receptacle, this cage preferably being of cylindrical form and of a length substantially equal to the inside length of the can. It is shown as open at the ends and is provided with two sheet metal plates 16 and 17 respectively, one being a flat plate spaced from the outlet end and the other conical at the inlet end and each fitting within thecage 15. Each of these plates also is provided with a central circular opening therethrough. In these openings is arranged a cylindrical tube 18 also of wire cloth or other material having openings therethrough for the passage of water. Thiscylinder projects" at the ends through theopenings in the metal plates 16 and 17 and when these parts are assembled, the central cylinder is located centrally in the outer cage and held in that position. Its ends project into the two couplings 11 and 12 so as to center the whole device. The end of the tube'18 is contracted to form a guide and a positive stop to the passage of large particles of soap or disinfectant. One or both of the plates 16 and 17 is made removable, the other one can be fixed to one the form of a cylindrical cake of solid disin- 105 fecting soap or the like having a central The water passing through the hose x or both of the cylinders 15 and 18 if desired.

plates is removed, the soap inserted, the cylindrical cage 18 inserted in the soap and the plate or plates placed at the ends of the soap inside the cylinder 15. These parts then are handled as a whole and are inserted in the casing 10 and held therein by the replacement of the cover 1 1. Then the two couplings are secured to the ends of hose sections or if desired, one to a hose section and the other to a sill cock or nozzle.

The operation of the device is very simple, part of the water coming in through the inlet 11 engages the convex conical surface of the plate 16 and is forced outwardly into the space between the cylinder 15 and the casing 10 so as to surround the soap.. This water'or solution then passes to the outlet through the space between the plate 17 and the end of the casing. The water which enters centrally passes through. the wire cloth tube 18 and dissolves the inner surface of the soap surrounding that tube. Both the outer and the inner streams of water unite to pass out into the hose through the outlet 12.

One of the important things to be noticed is that as the soap wears away, both on its outside and on its inner surface, which surrounds the tube 18, the outer surface of the soap will decrease in area but there is a Substantially corresponding increase of area of the inner surface which is exposed to the current passing longitudinally through the tube 18. It will beseen, therefore, that as the device is'used there is nomaterial tendency for the solution to grow weaker, which remedies a fault found in these devices as heretofore made so far as I am aware. This is true whether the soap is solid, viscous, or in one or more pieces. In addition to this, the device is kept perfectly centered without the use of external centering'devices and the water is distributed positively around the exterior of the soap as well as through its center so that all parts are acted upon by the water. Moreover, the plates 16 and 17 protect the ends of the soap especially the one nearest the inlet from the rapid action of the enteringwater and. thus add to the durability and efiiciency of the device.

In this way the rapid solution of the ends .of the cake of soap is avoided and it is found in practice that the soap does not decrease in length to any great degree wh1le it is being used up.

In Fig. 4 I have shown a modlficatlon 1n which the nozzle indicated in Fig. l is entirely dispensed with. In this case the inlet of ,the device is the same as in Fig. 2 but the outlet is modified. The casing has a fine outlet opening 31, or a row of them, for the stream ofsolution. Extending from this end of the casing to a point in front of this opening but somewhat spaced therefrom is a plate 32 in position to be engaged by the discharged solution and located angularly so as to distribute a fine spray. This plate is shown as formed of thin material so that it can be bent slightly back and forth to regulate the spray. In this form the outside cage 15 is shown as centered by a fiat plate or washer 33 having a plurality of arms 34. bent at right angles from its edges and then again bent to form projections 35 in a plane parallel to the plane of the plate. These projections 35 engage the walls of the container and serve to center the end thereof. In this case the interior cage or tube 18 is centered simply by extending through a hole on the plate.

Another way in which the invention can be employed is in the original packing of disinfectants and similar substances. For this purpose the barrel, keg or other container 10, (Figs. 5, 6 and 7) no matter what its size, can be provided with screen devices similar to those heretofore described with the soap or other soluble substances in them in such condition that when the barrel or the like is received it is necessary only to screw the hose on the two ends and 'use the contents in the manner heretofore described herein. In this way the receiver of the goods does not have to take the soap or the like out of the barrel. vAlthough the forms shown in the first four figures can be used in this case, I have shown them somewhat modified. The entire device for holding the soap or the like is made up of a single screen cloth having two portions 15 and 18 connected by a piece of woven cloth 40 integral with them. These are wound up in such form that the connecting piece assumes a spiral form, as shown in Fig. 6Q The end is connected to the edge of the outer member 15 so as to constitute a wire cage as before. The ends are kept in place by two plates 16 which in this case are both shown conical and these are provided with outwardly extending projections 35 for the same purpose as has been described hereinbefore. In this case the wire portion of the device can be surrounded inside and outside by paper or the like and the soap cast in it so as to fill the entire space between the inner tube 18 and the outer cylinder 15*. Then after one end of the barrel or the like is headed up, the soap and its container can be placed inside and the other head then put in. This permits the use of the device without unpacking the soap, which is often of a disagreeable nature, and it also permits of the sending of the barrel back to the manufacturers to be refilled. It is to be observed that in all the forms shown the surfaces of 1 the soluble substance which come into contact with the water are maintained of substantially constant area so as to keep the strength of the solution substantially constant. v

In all the forms shown, the holding device for the soap or the like can be removed from the container and refilled, either at the factory or elsewhere. In putting it back in the container it is easily put in place and centered and it is held in place by attaching the cover or heading up the barrel.

It is to be understood that although I have referred to this-invention as used for soap and for spraying trees, plants, buildings, etc., yet I am aware of the fact that the invention can be used for various o-ther purposes such as the application of paint and white wash to buildings or the distribution of ordinary soap for cleaning purposes and the spraying of disinfectants or insecticides not containing soap but containing other ingredients which render them solid or viscous at ordinary temperatures and yet soluble in water.

Although I have illustrated and described only three forms of the invention, I am aware of the fact that many other modifications can be made therein by any one skilled in the art without departing from the scope of the invention as expressed in the claims, therefore, I do not wish to be limited in these respects, but
